Document repl 'host' setting

The [repl] block also supports setting 'host' to change where the repl service
is listening to. This documents this setting, while also warning that changing
it from 127.0.0.1 is not recommended for a production environment.

PDB-407 Fix bug in init script for fedora

While working on acceptance tests we've found a bug with the init script for
Fedora and 1.5.x specifically. That is, the ps that was being returned during
find_my_pid did not return the fully qualified file path to be matched
against. This patch simply takes the basename from JAVA_BIN and uses that
in the match instead.
